Episode 11 - Advanced Bindings and Core Data

We finally feel strong enough to deviate from the Textbook and cover more advanced topics. We introduced two advanced topics in this Episode -- Advanced Bindings with multiple Array Controllers and Core Data. We showed how to create an application with multiple windows (a window and drawer) and connect multiple NSArrayControllers. Finally, RaiseMan application is replicated with Core Data and zero lines of code.

Core Data History

• It is Not a Database
• Rather, it is an infrastructure for saving objects
and retrieving them from persistent storage
• Does not rely on Cocoa Bindings
• Rather, it does integrate with bindings and it
leverages its technology
What Core Data is not:

Object Management

Core Data with MVC

• Design our Model
• Implement Relationships
• Implement Management
Managed Object Context
